But you stated that short-selling lowers the price of a stock. Why doesn't the short-covering raise the price?
The answer is that short-selling or short-covering can give the appearance of "momentum" for those traders who pay attention to such things. The short seller hopes to create such an illusion, and then close out his position before things return to normal.
The savvy investor, meanwhile uses the temporary price depression which can be caused by short-sellers. Us "bottom feeders" (for I've done this at times) are what stop the "momentum" downwards.
I expect it's because of that nigger-loving cocksucker. That slanteyed chink won't censor the ass-shit-sucking nigger bastard Greggie, so maybe hiding the board is the wimpy little bitch-boy's way out.
